Divided and this application led November 16,1911. Serial No. 660,546.

b all whom it may concern.'

lie it known that l, FREDERICK G. SAR- onx'r, a citizen of the United States, residing et vlllestford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Delivery Device for llVool-lllashing Machines, of which the following is a specication.

rihis is a division of my application for patent, .Serial No. 507,051, filed July 12, 1909, on wool washer.

The principal objects of the invention are to provide a. wool washer with a delivery device or carrier of such form that the parts which come into Contact will wear uniformly and thus permit of a smooth and even operation even after long continued use; also to provide a construction in which the front end of the delivery mechanism slides on ways while the rear end is supported by the usual connecting arm and crank by which it is operated.

Reference is to be had to the accompanying drawing in which the figure is a side elevation of a part of a wool washing` ma* chine constructed in accordance with this invention.

In these drawings the tank or bowl 10 is shown as provided with a screen or support 11 for the wool, a rake 12 for moving the wool along the support, and a delivery device 13 for taking the wool up out of the washer and delivering` it to the rolls 14. As is well understood in this art, this delivery device is operated by a crank shaft 15 and a link 16, a movable link 17 being shown for lifting the delivery device at the proper time. Extending upwardly from the screen 11 the tank is provided with a curved or inclined surface or table 18 along which the delivery device is adapted to work, and on the inside of each outer wall the tank is provided with a guide 19 having a curved surface 20, which at the top is provided with a flattened portion 21 and is substantially parallel at all points with the table 18. The link 16 has a loose rod 22 by which the delivery device 13 is pivoted, and on the ends of which are rigidly mounted rockers or sliders 23 which slide along the surfaces 2O and 21 as the shaft 15 rotates. These sliders are Xed with respect to the rod and delivery device so that they will rock slightly with the motion of the delivery device. Thus although they may wear as they move along the guide surfaces, the wear will be smooth and uniform and the travel of the delivery device will be the same after the machine has been in use for many years. This is an advantage over the roller constructions heretofore employed, as shown in my prior Patent No. 872,020, because they do not wear uniformly and they tend to irregularly wear away the surface 20. By making this latter surface of a greatly inclined and uniformly curved form and having it slope away in a flattened curved surface 21, the motion of the delivery member is made smooth and even, and at the end it has a substantially straight advancing motion to take the wool to the rolls.

Under the surface 18 is a space in which the water is comparatively clean as the wool has lost a large proportion of its foreign matter before it reaches this position. As this space is higher' than any other space in the tank located below the path of travel of the wool, it will be seen that the natural settling of the water will leave this water clearer than in any other part of the tank. In addition to this, the space can be separated from the rest of the tank by the surface 18 and by a continuation 25 of the screen, so that the water entering it will be screened. For these reasons this water will ordinarily be clear enough so that it can be used over again. At this point an outlet pipe 30 is provided in the side of the tank.

rlhe currents of water from the rear end of the tank circulate mostly above the screen, and consequently, cannot act to stir up the sediment below it. For this reason, the water in the space'from which it is discharged into the outlet pipe 3() is rendered substantially clear and free from sediment.

llVhile I have illust-rated and described a preferred embodiment of the invention, l am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claim. Therefore l do not wish to be limited to all the details of construction herein shown and described, but

a lower surface movable along said surface, and a delivery device lixed to the rod.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
